संकल्पना:

शाफ्ट की कठोरता को ध्यान में रखते हुए,

d व्यास वाले ठोस शाफ्ट में प्रेरित अधिकतम अपरूपण प्रतिबल, T घुमाव आघूर्ण को संचारित करने के लिए, निम्न द्वारा दिया गया है,

\(\tau_{max}\;=\frac{{16T}}{{\pi d^3 }}\)

बाहरी व्यास do और आंतरिक व्यास di वाले खोखले शाफ्ट में T घुमाव आघूर्ण को संचारित करने के लिए प्रेरित अधिकतम अपरूपण प्रतिबल।

.\(\tau_{max}\;=\frac{{16T}}{{\pi d_o^3 (1-K^4)}}\), जहाँ K बाहरी और आंतरिक व्यास का अनुपात है, \(K =\frac{{d_i}}{{d_o}}\)

व्याख्या:

दिया गया है:

do = D, di = d

⇒ τmax = \(\frac{16TD}{\pi(D^4 - d^4)}\)
